Visual, functional, and dimensional analysis was performed on the returned device.The reported obstruction of flow could not be confirmed, and the reported break/rupture at the purge port could not be confirmed; however, a leak was noted at the proximal region of the sheath.Further investigation revealed that the sheath appeared to have a rupture, resulting in a gap, from which the aforementioned leak was noted.The cause of the leak is consistent with the sheath damage.Functional testing could not be confirmed due to the device condition.Dimensional inspection revealed the purge hole inner diameter met the specifications.A review of the lot history record identified no exception issue for this lot related to reported issue.Additionally, a review of the complaint history of the reported lot did not indicate a lot specific quality issue.The investigation was unable to determine the cause of the leak finding at the proximal region of the sheath.Although the cause of the sheath damage could not be determined, it may be possible that over-pressurization during flushing the device contributed the sheath damage; however, this could not be confirmed.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.

It was reported that during device preparation, when the dragonfly opstar was purged with contrast using a 3cc syringe, the syringe was unable to be pressed.While pressing the syringe harder, the purge port ruptured.No patient was involved with this device.Another catheter was used to complete the procedure with no adverse patient consequences.There was no clinically significant delay.No additional information was provided.Return device analysis identified a longitudinal tear on the sheath.
